#36 ELAC Debut 3.0 DF63: $1,298 per pair Amazon eBay

Pros: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The dedicated midrange driver keeps distortion low even at higher output, avoiding the intermodulation grain typical of two-way bookshelf designs. The waveguide keeps high-frequency directivity well controlled, and overall horizontal directivity is good up to about 2kHz. Harmonic distortion looks good at both 86dB and 96dB, and multitone distortion stays below the reviewer’s 3% threshold. A shallow bass rolloff (F3 71Hz, F10 29Hz) lets it extend fairly low without a hard cutoff. Preferred by the reviewer over the similarly-priced Polk R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk R700 as well. Measured bass extension of 71Hz (-3dB), with a measured sensitivity of 86.6dB.

Cons: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals. A mild peak around 10kHz makes shakers and similar high-frequency percussion jump too far forward in the mix; needed about 2dB of EQ to tame in testing. A dip in the 1-3kHz range gives the speaker a warm, slightly veiled character: the reviewer suspects the tweeter crossover point (around 2-3kHz) is set a bit high and could be lowered to fill this in. Directivity shows a noticeable handoff mismatch around 2.5kHz where the midrange driver hands off to the tweeter, though it’s minor at the -6dB point. Vertical directivity is narrower than horizontal, so listeners need to stay close to the tweeter axis. Low EPDR (about 1.5 ohms minimum) means a Class AB amplifier should be well-ventilated. Best positioned pointed directly at the listener and closer to the front wall: toeing it out into the room causes too much high-frequency rolloff.

How it compares: Just above it: Emotiva Airmotiv T2+ - $350 more, 2.9Hz higher bass extension (-3dB). Just below it: Polk Reserve R500 - $19 cheaper, 0.4Hz lower bass extension (-3dB).
